Dont be misled by the title, i'm not a chao keng king. But one of my section mate is. I just Attend B and Attend C twice.
Attend B = Excuse from light duties for 2days + 1 day recovery day. Meaning to say, ya get 3days off from exercising and punishment.
Attend C = Unfit for duty. Either ya will send to sickbay and put on drip or ya're able to go home and rest. Number of days are depend from the captain (doctor) in medical center. They might be a captain but they are some bunch of cheebye kia that aint consistent in the status slip. For example, Room 1 will always keep sick bay to those having high fever, Room 2 will always give Attend C for those high feverer, Room 3 will always give nonsense status slip.
I dont know whether am i suffereing from low blood pressure but when i completed my 16km route march, i suffered from high fever and vomitting. It was bout 10pm at that time. And worst thing of all happen is that, the blood pressure machine cant detect my blood pressure and took 6 times to get my blood pressure. And when captain saw me having high fever and low blood pressure, he asked me whether i wanna put on drip because low blood pressure victim might pass out anything. Whatever it is, just say that ya got needle phobia and ya wont be on drip already! Lol.
If ya wanna keng, ya can just go medical center say that ya got chest pain all these, ya can get Attend B easily.
At this point of time, ya will realise i'm talking out of point, but WHO CARES? LOL!
When ya go in, ya will naturally learn the skill of chaokenging.
CHAOKENGGGGGGGGGGGGGGGGGGGGG~!~!
